Hey guys, I've bought my parts for a custom build and they're all coming tomorrow (can't wait!). I've purchased a cheap (legal, i made sure) version of Windows 7 Professional. It came with a Dell Reinstallation CD and a Product ID key for activating Windows. I'm just curious that the reinstallation disc will work well? I've installed a Windows 7 ISO and burned it onto another CD just in case this Dell one has some problems but should it be okay? Also would a Dell Windows key work with another type of download? A non dell Windows 7 Pro download? Thanks guys
